Abstract:For power systems with large scale wind power, the variability of wind power output may cause the fluctuations of voltage at connection point. To meet the requirement of voltage level, reactive power compensation devices act too frequently by traditional methods. So an action strategy of reactive power compensation devices that can adapt to the wide range fluctuation of wind power is put forward, in which a province power grid with large wind power integration in 2015 is simulated in steady state by using of PSASP, network loss is used as evaluation indexes, and action times of reactive power compensation devices is used as the optimized objective to analyze summer peak load under conditions of different wind power output. The simulation examples show that this strategy can significantly decrease the action times of reactive power compensation device under the condition of wide range fluctuations in wind power output. The conclusion can provide a reference for the operation control and planning of the power system, which has engineering practicality.
